The flat is good for 2-3 people. The area Thonglor is very safe and good for families too. The host is kind and helpful. However, it is a bit far from metro stations. So, it may take you longer to get to the main tourist locations of Bangkok. Also, if you are 2 or more than 2 people, there are some practical difficulties as the host insists on keeping the keys together which was very inconvenient.
